Why spouses depress each other: A cross‐national study to test the shared resource hypothesis in depressive symptom concordance within older adult couples

The shared resource hypothesis suggests that married couples share the same environmental resources, which shape their health concordance. This study tests its cross‐national applicability. Cross‐sectional 2012–2013 Health and Retirement Study data from China, England, Mexico, and the United States were analyzed. Heterosexual couples (age ≥60) who were married or partnered were studied (N = 20,565 pairs). Dyadic data were analyzed by multilevel models to examine the effect of self and spousal social and physical health statuses on depressive symptoms. Regression models were used to test the relationship between couples' shared resources and depressive symptom concordance. Results indicated both husbands and wives' depressive symptoms were associated with their own and spouses' social and health statuses. Most couple‐level resources were insignificant predictors for Chinese and Mexican couples' concordance, but having more social and financial resources was associated with higher concordance among British and American couples. Self‐reported health was the most consistent predictor in all countries. The shared resource hypothesis was more applicable to depressive symptom concordance within couples in the United States and England, but not in China and Mexico. Couple‐centered intervention is suggested for clinical practice, and the spousal effect should be considered in policymaking.     

Gender,work, and childcare in Kazakhstan,Mongolia, and Russia

The current study seeks to understand the nature of gender relations within a post‐Soviet welfare model in Kazakhstan, Mongolia, and Russia. On the basis of the analysis of key labour market indicators, parental leave, and childcare policies, it finds that the welfare models in the three countries are hybrid, and neither authoritarianism in Kazakhstan and Russia nor democracy in Mongolia lead to substantive gender equality outcomes. Persistent gender inequality in these countries is underpinned by the neo‐liberal approach to welfare provision, conservative social norms, and limited agency of civil society to influence the policy agenda. Nonetheless, these states have distributed to the population with an emphasis on working mothers, and this policy choice has been driven by economic, demographic, and political considerations, which ultimately serve to support, rather than transform, the patriarchal power structure in these societies.     

Sexual Orientation as a Peripheral Cue in Advertising: Effects of Models’ Sexual Orientation,Argument Strength,and Involvement on Responses to Magazine Ads

This study examines how sexual orientation of couples featured in magazine advertisements affects heterosexual viewers’ responses using the elaboration likelihood model as a framework. A 3 × 2 × 2 × 3 experiment tested effects of sexual orientation, argument strength, involvement, and attitudes toward homosexuality on heterosexuals’ attitudes toward the couple, advertisement, brand, and product, purchase intentions, and recall. Results indicate that consumers were accepting of ads with lesbian portrayals. Participants showed more negative attitudes toward gay male portrayals, but attitudes toward heterosexual and lesbian ads were similar. This effect was moderated by participants’ attitudes toward homosexuals. Low-involvement consumers showed more negative attitudes toward homosexual portrayals than toward heterosexual portrayals, indicating that sexual orientation may have served as a peripheral cue negatively impacting attitudes toward the couple and ad under low elaboration. These effects were not observed for attitudes toward the brand and product, purchase intentions, or recall.

考虑项目关联关系的R&D网络风险传播建模与仿真

考虑同一企业内不同项目间关联关系的情况下,基于研发项目的数量将研发网络分为不同子网络。借鉴SIS模型构建了R&D网络风险传播动力学模型,并对该模型进行了数理解析与仿真分析。结果表明：R&D网络风险传播阈值是由不同子网络的拓扑结构以及企业内不同项目间的关联程度共同决定的;考虑项目关联的研发网络风险传播阈值小于不考虑关联关系的研发网络风险传播阈值;项目间关联关系的企业个数及项目间的关联程度对风险在不同子网络上的传播速度与传播范围均具有影响。该研究成果对于提高研发网络抗风险能力具有重要意义。     

一类稀疏投资组合双层参数估计模型及其应用

带基约束的投资组合问题是近年来投资组合领域的热点问题,但是参数不确定性直接影响了模型的效果。带基约束的投资组合问题所涉及的参数不仅包括以往研究认为非常重要的预期收益率,还包括控制投资组合规模的稀疏度,尤其是最优稀疏度估计方面的专门研究还十分匮乏。为了使带基约束的投资组合模型更好地为投资决策服务,本文从投资者效用出发,用双层规划的思想构建了带基约束的投资组合双层参数估计模型。然后根据模型的特点,设计了无导数优化算法框架,并基于ADMM对算法子问题进行求解。本文实验针对真实的市场数据给出了预期收益率和最优稀疏度的估计,接着通过与等权重策略和含上下界约束的均值-方差模型进行比较,说明了模型及算法的有效性和实用性。最后,将本文提出的双层参数估计模型推广到了更一般的形式。     

基于波动持续性的最优组合构建与分散化研究

构建恰当资产组合来减少风险, 是投资组合理论研究的重要目标.由于金融时间序列的波动往往会伴随着持续性特征, 该种特性会增大组合未来收益的风险.本文通过构建随机波动模型序列持续性最优投资组合模型, 以降低金融资产波动的持续性特征对组合收益波动的影响;并通过研究其分散化水平, 考察该投资组合构建方法的有效性与稳健性.研究发现:与均值方差的组合模型相比较, 序列持续性组合的风险分散化水平更好.此研究在资产组合选择方面, 具有较为重要的理论价值及实践意义.
